The Certina DS Sport Chronograph is an exciting, race inspired men’s watch, with Certina’s 1/10 second Precidrive movement. It has a black dial, rubber strap, and green chrono stopwatch timer hands.
Review of the Certina C027.417.17.057.01.
The Certina DS Sport Chronograph Watch uses Certina’s high-accuracy, Swiss, quartz Precidrive movement. It keeps time accurate to within + or – 20 seconds a year.
It has very easy to read, high contrast elapsed time chronograph dials.
The long green hand is the 60 second counter. The highlighted dial in the upper left is the 30 minute counter. And the dial on the upper right that spins fast is the 1/10 second counter.
The dial on the bottom is the second hand for the clock function, and hence is running all the time.
There is an easy to read outer bezel that is marked from 0-60.
There is also a date counter in the lower right at the 4 O’Clock point.
The hands, hour markers and the 12 hour mark are all luminescent, so they glow in the dark.
The crystal is a scratch-resistant sapphire crystal.
This watch is water-resistant with the Certina DS Double Security standard for water resistance.
It is certified to 100 Meters, which is 330 feet. Combined with the rubber strap, this watch is well suited to wearing in the ocean while swimming, light diving and snorkeling.
